This light-rail transit line will run along Toronto’s Eglinton Avenue between Mount Dennis (Weston Road) and Kennedy Station. Part of the Government of Ontario’s light-rail transit plan for the city, this 19-kilometre corridor will include an 11-kilometre underground portion between Keele Street and Laird Drive. When running at street level, the line will carry passengers in dedicated right-of-way transit lanes separate from regular traffic with priority signaling at intersections.

Travelling at an average speed of 28 km/h, it will link to 54 bus routes, three subway stations, and various GO Transit lines. The capacity of the LRT vehicles is 15,000 passengers per hour per direction, with the flexibility to easily remove or add cars. In August of 2016, tunnelling work was completed on the 10-kilometre underground portion of the project. Projected ridership is 5,400 passengers per hour in the peak direction by 2031.

In August of 2017, the project reached a major milestone with the laying of the first piece of track, part of a turnout track connecting Mount Dennis station with the storage and maintenance facility. The facility represents the first significant portion of the project to be completed, which will take place in 2018. Overall project construction is estimated to be completed by 2021.
